Hi every one,
What is the right way to do a Hypothesis testing for Mean value in Alteryx.
Do you have a sample flow, previous post or a guide?
Thanks.
Hi @huynv96 ,
if you want to use Test of Means tool to check, if the Mean of group 1 shows a significant difference to the mean of group 2, you simply have to provide detail observation data to the Test of Means tool. You need the field to identify the group and a "measure" field (must be numeric). Welch's t-test is performed to test, if the groups have identical means. I've added a very simple sample workflow, configuration is really straightforward. Do this help in any way?
Best,
Roland
@huynv96 @You might want to look into the rest of means tool that’s a part of the predictive tools install.
Hi @RolandSchubert
Thank you for your respond.
I have issue about version so i can not open your workflow you attach.
I create a simple workflow and config as you guide, this is the result.
Can you explain more about T-test value? T-test for what exactly hypothesis in this case?
I see p_value very small, so can it means that we reject null hypothesis (Mean male = mean female) and conclusion is mean male and female is difference?
Thanks
